阅读下面这首古诗，完成两小题。
                                                                                          赋得暮雨送李胄
                                                                                                韦应物
                                                                                楚江微雨里，建业暮钟时。
                                                                                漠漠帆来重，冥冥鸟去迟。
                                                                                海门深不见，浦树远含滋。
                                                                               相送情无限，沾襟比散丝。
